Eh, it's okay. I like the silhouette-based graphics a lot, but the gameplay is in a pretty rough state. The first and most obvious issue is that J and H are pretty unintuitive keys for sniping. Given that this game uses WASD and won't have mobile integration, mouse aiming makes a lot more sense for shooting. The controls also feel weird regarding the platforming, specifically some of the jumps which require high precision.
Probably the biggest issue is the lines that you and the enemies have to telegraph where they're aiming. The limited range (both for the player and enemies) is inconsistent and makes it frustrating to know when and where you can be hit. Some kind of delay and audio telegraph would be nice, as it would give the player a chance to run the other way or try to quickscope enemies. The meat and potatoes of the game (running into the aiming path of an enemy, then sniping them before the line rolls over you) became intuitive with enough practice but never really felt enjoyable.
It's not a bad concept, but it feels clunky, as the actual challenge (timing when to come out of hiding and sniping quickly) feels pretty far removed from the actual concept of a run and gun.
